First time going to see fertility specialist

My husband who is 39 and myself, 28 have been married for 3 years this August. We've been trying for a baby for about 2 years now. We are finally going to see a fertility specialist on June 24th. Can anyone else who has been to one tell me what I might expect from the visit? 
I've already had an HSG done (normal results) and the day-3 blood work done also with normal results. So my tubes are clear and I am definitely ovulating. 
Only issue is low volume for my husband. 
Anyone else out there with the same or similar issues?
